Ovid vs. PubMed

Ovid Logo
(These comments pertain to UTHCT's Ovid system and PubMed. Every point may not apply to systems at other sites.)

Advantages:
* Allows easy limitation to Local Holdings or Full Text.
* Other limits (i.e. language, human, etc.) are easily accessible on main search page.
* Provides possible MeSH (National Library of Medicine Medical Subject Headings) terms when searched terms are not MeSH terms.
* Local Messages indicate if the Library has the journal that an article is located in.
* Local Messages include hypertext links to the Library's electronic journal list.
* Search strategies may be easily transferred to Ovid CINAHL.
Disadvantages:
* Database updates are behind PubMed.
* Available only to authorized UTHCT users.

Advantages:
* Rapid database updates.
* Related Articles feature.
* LinkOut provides linking to available full-text of articles and to print holdings information (UTHCT users only).
* Links to free full-text when available.
* Links to genetics and biomolecular databases.
* Includes MeSH Database function for identifying NLM Medical Subject Headings.
* Search can be limited to subsets such as Core Clinical Journals, Nursing Journals, Cancer Journals, AIDS, and others.
* Available to the general public via any ISP (internet service provider). (Does not include LinkOut links to subscribed journals.)
Disadvantages:
* Proprietary links to journals are confusing if no subscription is held.
* Full-text limitation available but not straightforward.
* No on-screen instructions for Boolean search syntax.

CSS: This specification defines Cascading Style Sheets, level 2 (CSS2). CSS2 is a style sheet language that allows authors and users to attach style (e.g., fonts, spacing, and aural cues) to structured documents (e.g., HTML documents and XML applications). By separating the presentation style of documents from the content of documents, CSS2 simplifies Web authoring and site maintenance.
XHTML 1.1: This Recommendation defines a new XHTML document type that is based upon the module framework and modules defined in Modularization of XHTML [XHTMLMOD]. The purpose of this document type is to serve as the basis for future extended XHTML 'family' document types, and to provide a consistent, forward-looking document type cleanly separated from the deprecated, legacy functionality of HTML 4 [HTML4] that was brought forward into the XHTML 1.0 [XHTML1] document types. This document type is essentially a reformulation of XHTML 1.0 Strict using XHTML Modules. This means that many facilities available in other XHTML Family document types (e.g., XHTML Frames) are not available in this document type. These other facilities are available through modules defined in Modularization of XHTML, and document authors are free to define document types based upon XHTML 1.1 that use these facilities (see [XHTMLMOD] for information on creating new document types).
WAI-AAA: These guidelines explain how to make Web content accessible to people with disabilities. The guidelines are intended for all Web content developers (page authors and site designers) and for developers of authoring tools. The primary goal of these guidelines is to promote accessibility. However, following them will also make Web content more available to all users, whatever user agent they are using (e.g., desktop browser, voice browser, mobile phone, automobile-based personal computer, etc.) or constraints they may be operating under (e.g., noisy surroundings, under- or over-illuminated rooms, in a hands-free environment, etc.). Following these guidelines will also help people find information on the Web more quickly. These guidelines do not discourage content developers from using images, video, etc., but rather explain how to make multimedia content more accessible to a wide audience.
