PO references

The abbreviation PO_REF is used for dbxrefs (for definitions, synonyms, or general use) that do not have a PubMed ID, ISBN number, or stable URL. This can include older books and journal articles, as well as unpublished data sources.

Each reference has its own wiki page, with the name PO_REF:ID, where ID is a unique 5 digit number that us used to create a link to the url in AmiGO (PO's web browser).
