LSS is "Locks, Safes and Security:
An International Police Reference", written by one of the foremost authorities in the field, Mr. Marc Webber Tobias.
It is quite possibily the most important reference work in the field to date. 40 chapters, 1400 pages across two volumes. Additionally an electronic version is also available.
