Chemical Information Sources/Keeping Up and Looking Back

Current Awareness, Reviews, and Document Delivery

Introduction
With the tremendous volume of primary chemical literature appearing each year, chemists need efficient methods for identifying newly published articles focused on their research areas. Current Awareness or Auto-Alert, services provide a range of simple and effective tools that can help scientists keep up with newly published articles critical to their research. The numerous Current Awareness options described below make it possible to: define an area of interest and receive alerts when new articles are published in that area; have tables of contents sent to you when journals you specify publish a new issue;  and notify you when a given article is cited.

Just as Current Awareness services are useful for managing newly published literature, Review Articles can be useful for sifting through previously published literature, since they typically survey large bodies of literature, summarize significant findings, and provide critical reviews on particular topics. This can be especially useful when there is the need to get up to speed quickly on an new topic, or when beginning a large project. Methods for identifying research articles and book chapters are given below. Since it is likely that all of the items needed will not be found in any one local library, it may be necessary to use Document Delivery or Interlibrary Loan services to obtain articles and books, these services are described below.

Current Awareness: Auto-Alerts
An impressive variety of current awareness services, or auto-alerts, are available to help chemists stay current on the published research literature. Auto-alerts allow you to save a search specific to your research interests, have it automatically re-run each time new citations are added to a database or publisher website, and have the new citations delivered to you, as an email or an RSS feed. Other names for these current awareness services include: email alerts, and SDI (selective dissemination of information).

Auto-alerts were formerly available only from subscription article/research databases, but are now also available from: publishers, Google Scholar, and additional less formal (and generally less comprehensive) options including: Twitter feeds; user communities or social networks; podcasts; YouTube Channels; smart phone and tablet apps; and search widgets.

To identify the auto-alert(s) that best meet their needs, researchers need to be aware of the different types that are available:

The Search Alerts, TOC Alerts, and Citation Alerts sections below list options for creating various types of auto-alerts using chemistry and general databases, major chemistry publishers, and Google Scholar. Each section indicates what each type of alert is Best for, and which option is the Best choice, for setting up an alert (database, publisher, etc.) Within each section, the most robust options are listed first. Each entry includes: a brief description; the provider's name for the alert;  links to web pages or PDFs that explain how to set up each type of alert; coverage;  requirements for access; and available formats.
 * Search Alerts: Allow you to save a search on a: topic, substance, reaction, author, or journal name (options vary by database and publisher).  Your search is rerun either when new records are added, or at an interval you specify.
 * TOC (Table of Contents) Alerts: Send you the table of contents when a new journal issue is published (also called journal issue alerts).
 * Citation Alerts:  Notify you when article(s) you specify are cited.

Search Alerts
Allow you to save a search on a: topic, substance, reaction, author, or journal name (options vary by database and publisher). Your search is rerun either when new records are added, or at an interval you specify.
 * Best for: staying current on a topic, substance/reaction or author
 * Best choice: article/research databases, significant publishers in your field
 *  A) Database Search Alerts :
 * Most databases listed here require subscription (paid) access, which is generally provided through your academic institution library or employer. For those with access, a free login/account is usually required to use the alerts service.
 *  CHEMISTRY DATABASES :
 * SciFinder: Keep Me Posted (KMP): KMP Alerts can be set up for both topics and substances.
 * Coverage: SciFinder indexes all of chemistry and chemical aspects of other fields and includes journal articles, patents, dissertations, meeting abstracts, and additional sources.  This makes SciFinder Alerts the most robust option for staying current on the chemical literature.
 * Required: Access to SciFinder, personal login (a prerequisite for SciFinder access).

Additional Options
Current Awareness services began in the late 1950s, well before both Internet access to article databases, and digital publication of journal articles, became ubiquitous. During the 1950s and 1960s, these services were commonly called “selective dissemination of information” (or SDI). These services used computer programs to identify and collect abstracts for recently published journal articles. “Interest profiles” (searches on topics, based on keywords) were developed for broad areas. The resulting collections of abstracts, focused on broad topics, were distributed in print to subscribers.

Some services based on this model are still available (see below). Their primary advantage is that they offer a more thorough literature search than can be accomplished via free options (Google Scholar, Journal TOCs, etc.), and although these services are fee-based, they do not require on-going subscriptions to article databases.


 * STN:
 * Provides various search interfaces, analysis and visualization tools geared to information professionals, available from CAS division of ACS. Current awareness alerts are available from the STN Express and STN on the Web products. STN Current Awareness User Guide provides more information about the current awareness alert options avialable on STN.


 * Thomson Reuters Personal Alert:
 * Profile-based current awareness service, available from Thomson Reuters. Results delivered via email, sent daily or weekly.

Reviews
All of the sources in the previous section are aimed at making you aware of the existence of new primary literature as soon as it is available. REVIEW articles (or book chapters) serve a different purpose: they provide critical reviews of the published literature on particular topics. This can be very useful when there is a need to get up-to-speed on a new topic quickly, or when beginning a large project.

Reviews generally: are written by experts in a field, survey a large body of literature, summarize significant findings, and sometimes provide novel interpretations of results. Compared to “standard” journal articles, reviews generally: do not present new results, are longer, and provide substantially more references. Reviews may be published in: primary journals, conference proceedings, journals that specialize in publishing reviews, serial works that look like books, or multi-volume monograph sets. Examples of sources for reviews are given at the end of this section.

Finding Reviews

Many, but not all databases, permit searchers to limit results to only review articles, often as a second step after executing a search. The exact definition of what qualifies as a review article varies somewhat from vendor to vendor. To find reviews either use an article database, and limit your results to document type "review" (see below for instructions); or go to a known source for reviews in your area, such as those listed at the end of this section. The librarian at your institution, or a nearby academic library can help you locate additional sources for reviews.


 *  Using SciFinder to Find Reviews :
 * First conduct your search. From the results page, use the REFINE tab (on the right) to limit your results to DOCUMENT TYPE: REVIEW.


 *  Using Web Of Science to Find Reviews :
 * First conduct your search. From the results page, use the REFINE RESULTS tool bar (on the left) to limit your results to DOCUMENT TYPES: REVIEW.


 * Examples of sources for reviews:   Title (Publisher)

Document Delivery and Interlibrary Loan
DOCUMENT DELIVERY and INTERLIBRARY LOAN are terms used in libraries to refer to methods of providing access to items the library either does not own, or does not own in the desired format.

Interlibrary Loan refers to the process where a library patron requests an item not owned by the library they are affiliated with (i.e., their university or public library). The library where the request is made: identifies libraries that own the desired item, borrows it from another library, loans it to the patron, then returns it to the owning library. The lending library generally sets the due date, any usage restrictions (i.e., library use only), and has total discretion over what in their collection they choose to lend. Print copies of journals generally are not lent, instead a photocopy or PDF of the article is usually sent. Libraries generally pay fees to obtain materials through interlibrary loan, these may or may not be passed on to the end users. Because costs are involved, libraries generally provide Interlibrary Loan only for patrons affiliated with their library (e.g., the affiliated users of a university library are usually current students, faculty and staff at that university). Interlibrary loan policies and fees vary between libraries and institutions. Copyright restrictions can affect what can be lent, and in what format, particularly for digital materials (online books and journals). Document Delivery can refer to the practice of purchasing individual copies of items (usually articles or documents) to be given to the end user (perhaps at no charge or only a partial charge to the end user). Document Delivery can also refer to the practice of providing a digital copy of a print item owned by the library (almost always limited to articles and documents, may be fee-based or free).

Making an Interlibrary Loan Request: OpenURL Link Resolvers

Most libraries have online forms that allow patrons to request Interlibrary Loan or Document Delivery services. In addition, patrons can usually request an Interlibrary Loan from within article databases via OpenURL link resolvers, when their library does not own the desired item(s). OpenURL link resolvers are used by libraries to allow patrons to connect from article databases (and other resources) directly to subscription content (such as journal articles and books). If the library has a subscription to electronic content, the link will resolve to the online article or book. If the library has a print subscription, the link will resolve to the library's catalog, which provides the information needed to access the print journal or book. If online or print access is not available, most OpenURL link resolvers also include the option of requesting an item via Interlibrary Loan.

Examples of OpenURL link resolvers include:
 * Ex Libris SFX,
 * OCLC WorldShare License Manager,
 * Swets SwetsWise Linker,
 * Serials Solutions 360 Link,
 * Innovative Interfaces WebBridge,
 * Ovid LinkSolver,

and others. Many educational institutions apply "local branding" to the OpenURL link resolver they use.

Summary
Given the volume of scientific literature produced today, scientists need to be able to identify newly published items relevant to their research. A wide range of mainly web-based current awareness, or alerting services, have been developed to meet this need, providing an efficient and focused approach to the new literature. A focused approach for scanning the older literature is to identify review articles, either by using the search features in an article database, or by reviewing known sources for reviews in your research areas. When publications are needed that are not owned by the library you are affiliated with, Interlibrary Loan and Document Delivery can be relied upon to provide the needed materials in the majority of cases.
