Locatorplus does not exist in isolation; it is part of a larger ecosystem of resources provided by the National Library of Medicine. Understanding how Locatorplus connects with other NLM databases and tools can significantly enhance the user's ability to find the information they need.

One of the most important connections is with PubMed, the NLM's premier database of biomedical literature. While PubMed focuses on journal articles and abstracts, Locatorplus provides information about the availability of those articles in libraries around the world.

PubMed: A comprehensive database of biomedical literature, including citations, abstracts, and links to full-text articles.
Locatorplus: Provides information about the holdings of libraries, allowing users to locate physical or electronic copies of the articles found in PubMed.

Users often begin their search in PubMed to identify relevant articles and then use Locatorplus to determine whether those articles are available in a nearby library. Locatorplus may provide information about journals indexed in PubMed, showing which libraries subscribe to these journals and have them available for use.

MedlinePlus is another key resource provided by the NLM. It offers health information for patients and their families, covering a wide range of topics from diseases and conditions to wellness and prevention. While MedlinePlus is geared towards the general public, Locatorplus can be used to find more in-depth information on the topics covered in MedlinePlus.

MedlinePlus: Provides easy-to-understand information for patients and families about health conditions, treatments, and wellness.
Locatorplus: Enables users to find books, journals, and other resources that offer more detailed information on the topics covered in MedlinePlus.

For example, if a user finds information about diabetes on MedlinePlus and wants to learn more, they can use Locatorplus to locate books and articles on diabetes in their local library.

The NLM also provides a variety of other resources, such as:

Bookshelf: A collection of full-text books and reports available online.
ClinicalTrials.gov: A registry of clinical trials conducted around the world.
ChemIDplus: A database of chemical structures and nomenclature.

Locatorplus can be used to find materials related to these resources as well. For example, a user might find a reference to a book in Bookshelf and then use Locatorplus to locate a physical copy of that book in a library.

By understanding how Locatorplus connects with these other NLM resources, users can leverage the full power of the NLM's information ecosystem to find the information they need. This interconnectedness allows for a more comprehensive and efficient research experience, ensuring that users can access the right information at the right time.
