2. Definition Secondary literature refers to references that either index or abstract the primary literature with the goal of directing the user to the primary literature.

3. Secondary Information Resources Secondary Resources Indexing services bibliographic citation information (e.g., title, author, …etc.) Abstracting Services a brief description (or abstract) of the information provided by the article or resource cited

4. An Indexing System: Provides only bibliographic information that is indexed by topic. An Abstracting Service: Provides a brief description (abstract) of information contained in a specific citation.

5. Indexing & abstracting provide access to primary literature each of which covers: – different biomedical journals – meeting abstracts – newsletters – textbooks – other publications therefore, use of more than one of these resources often allows for more thorough information retrieval.

6. CD-ROM format (IDIS) Internet, such as Grateful Med or PubMed from the National Library of Medicine ( >). Print Format (paper)

7. Secondary Sources Print (Paper) Less Costly. Require more time. Can be searched by only one user at a time. Electronic More frequent updating of listings and information. Require knowledge of search strategy. Different systems use different indexing. Costly except for PubMed.

8. How to search in secondary resource ? Select your database. Identify your keywords. Use Boolean operators. Using limits.

9. Examples of secondary resources MEDLINE ®\ PUBMED Iowa drug information system (IDIS) International pharmaceutical abstracts (IPA) EMBASE Reactions weekly Google scholar

10. Identify your keywords Disease state Diabetes, hypertension and depression. Population Pediatrics, adults OR elderly. Drugs Metformin, Aspririn.

11. Use Boolean operators AND will combine two terms, returning only citations containing both of those concepts or terms. OR will include any citation where either term is used. NOT eliminates any references having the term that follows that operator.

12. Using limits Language of publication. Year of publication. Type of article (e.g., human study, review, and case report). Type of journal where publication is found.

13. Secondary Literature13 Achieve rapid access to literature information (any accumulated data..)

14. Secondary Literature14 Constitute the appropriate key term under which the information is filled in the relevant literature sources.

Med. 87:258S-260S (Nov 30 Supply) 1989. Indicative Abstract Single dose intravenous (IV) ciprofloxacin (I) and cefotaxime (II) are evaluated in a double blind study in male patients, 37 receiving, (1),300 mg, and 39 receiving II, 1.0 g, for preoperative prophylaxis in transurethral surgery. Examples of indicative and informative abstracts

27. Secondary Literature27 Single dose intravenous (JV) ciprofloxacin (I) and cefotaxime (II) are evaluated in a double blind study in male patients, 37 receiving, 1,300 mg, and 39 receiving II, 1.0 g, for preoperative prophylaxis in transurethral surgery. There were no symptomatic urinary tract infections or other infections after prostate and bladder surgery and no serious post surgery complications in any of the patients. Serum and prostatic tissue levels, as well as the tissue/serum ratios are included for 13 I patients. The most common side effect was postoperative nausea in 15 patients, 111 and 4 II patients. It is concluded that both drugs are effective and safe in reducing tree frequency of bacteriuria following transurethral surgery; there is no significant different between the 2 groups.
