Personal Digital Assistant Resources from the
National Library of Medicine

• The National Library of Medicine (NLM) has
  developed several information resources
  specifically designed for use on Personal Digital
  Assistants (PDAs).
• This workshop is an introduction to two of these
  applications.

• Locate and install the relevant software.
• Search PubMed/Medline via a specialized interface
  that is formatted for the PDA.
• Use filters and limits for advanced searching.
• View search results on the PDA.
• Browse journal abstracts on the PDA.
• Search ClinicalTrials.gov on the PDA.
• Provide feedback on these products.

PubMed Applications for the PDA

• PubMed on Tap 1.6
• PubMed on Tap (PMoT) is an research application
  for PDAs that brings MEDLINE citations directly
  to the PDA through a wireless connection to the
  Internet.
• PubMed for Handhelds
• A service that allows one to access the PubMed
  interface via a PDA equipped with an Internet
  browser.
• Both products are free.

PMOT Special Features

• PMoT features include
• PubMed search limits
• History of previous searches
• Save selected citations to the Memo Pad
• A clustered results option.

PubMed for Handhelds Special Features

• To use this service your PDA should have either a
  wireless or physical connection to the Internet
  and a Web browser.
• Users can also search offline by utilizing a
  product such as AvantGo (http//www.avantgo.com/).
  AvantGo allows Internet content to be captured
  and loaded to a PDA that has no Internet
  connection.
• Browse journal abstracts and search for clinical
  trials.

7
Hardware Requirements

• PMoT System Requirements
• Palm PDA or Smart-phone with an Internet
  connection via CDMA, GSM (the cell phone
  network) or through a WiFi LAN (802.11b).
• Pocket PC PDA or Smart-phone with an Internet
  connection.
• PubMed for Handhelds System Requirements
• There are no files to install thus it is platform
  independent. It works with Palm OS, PocketPC and
  Linux PDAs.
• Compatible with any Web browser AvantGo,
  Blazer, EudoraWeb, WebPro, Internet Explorer,
  etc.
• Has been tested with 802.11b, Bluetooth,
  infrared, wireless modem and desktop synch.

Updates

• As of June 2004 PMoT is available for the
  PocketPC.
• As of August 2004, the PubMed on Tap server no
  longer supports requests from clients to email a
  Citation. Because our users are not required to
  log in for this service, there is potential for
  abuse, and we need to close that hole. We
  apologize to those of you who use this feature.
  A workaround is to save the citation to the Memo
  Pad and either email that from your PDA or
  hotsync it to your desktop computer and email it
  from there.
• As of December 2004, the My Journals feature of
  PMoT was discontinued.
