Ovid MEDLINE Post Reload Communication – February 2019

 

Ovid MEDLINE Post Reload Communication

Dear Ovid MEDLINE Customer:

During the Ovid MEDLINE reload that was completed on 28 January 2019, we found that our “prem” database segment for “In-Process & Other Non-Indexed Citations” could no longer contain the increased data volume supplied by the NLM. This was mainly caused by the addition of the new “cited references fields” data to MEDLINE.
For this reason, we created 2 additional segments that combined with the original “prem” segment are now available as:

•   prew = Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations 1946 to January 28, 2019

The above database is a combination of 3 segments:

•   prem= Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations <2019>
•   prem2= Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations <2017 to 2018>
•   prem1= Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations <1946 to 2016>

The “prew” database only contains: In-Data-review, In-Process, and PubMed-Not-MEDLINE status records. The bulk of the records in “prem1” and in “prem2” are PubMed-Not-MEDLINE records going back to 1946 and even before. Because there are no fully Indexed MEDLINE records in any of these segments, tools like Mapping and Tree are not available. Please note that this change to the database for “In-Process & Other Non-Indexed Citations” does not affect AutoAlerts.

To avoid confusion, we have decided to hide the new “prew” database as well as prem, prem1 and prem2 from display. While there may be special reasons why some customers would like to see a separate display of the In-Process & Other Non-Indexed Citations database, we strongly recommend our Ovid MEDLINE customers only use the most complete segment:

•   medall= MEDALL Ovid MEDLINE(R) ALL <1946 to January 28, 2019>

The Ovid Support team will be pleased to help you to organize your Ovid Resources list. Databases can be added, removed and sorted in your resource list upon request. For instance, if you would like to have Ovid MEDLINE (R) ALL displayed in your Select Resources list, and have all other Ovid MEDLINE options removed, please contact Ovid Customer Support.

Date range searching
With this reload Ovid changed the indexing format for a number of field in order to limit searches by date range. As a follow up to this change the Ovid training team updated the corresponding article in our knowledgebase explaining the options for date range searching in Ovid MEDLINE. Date range searching is often used by information-specialist and researchers to see if new records were added to the database after an earlier review of the literature.
