Although normal searches (eg by author and keywords from title) in SOLO will return results covering both books and ebooks (where applicable) holders of an Oxford Single Sign On should independently open & check in both LexisLibrary (via the Sources Link)
AND Westlaw Books to see which titles are included in these databases.
Both services have (different) collections of important texts & reference works for the legal practictioner.
Holders of an Oxford Single Sign On are advised to check in the Commentary section of LexisLibrary, in Westlaw's Book collection to see if there are relevant titles there. The holdings in these databases can be hard to find in normal SOLO searches.
Subject searches to try in SOLO to find tax law titles include
Taxation - law and legislation
Income tax - law and legislation
Corporations -- Taxation -- Law and legislation
The name of a particular jurisdiction can added eg - Great Britain - so that the results are filtered.
Of course it is also possible to see if there are titles just dealing with a more narrow aspect of tax law. Some examples are:
Capital gains tax - Law and legislation
Charitable uses, trusts, and foundations -- Taxation
Gifts -- Taxation
Inheritance and transfer tax - Law and legislation
International business enterprises -- Taxation -- Law and legislation
Investments - Taxation - Law and legislation
Investments, Foreign - Taxation - Law and legislation
Tax administration and procedure
Tax shelters - Law and legislation
Value added tax - Law and legislation
Conversely, to find titles looking more at policy try
Taxation and/or Fiscal policy (with or without Great Britain etc as above. )
and/or remove the "law and legislation" element from your subject search & run it again.
