The two volumes on the Psalms written by bro. George Booker are amongst the most well-thumbed books on my bookshelf. The analytical approach taken by bro. George appeals to my way of thinking and I find them invaluable when considering the Psalms.
These are now available for download below, split into easily manageable files They are reference works, not commentaries (for bro. George's verse-by-verse commentaries, see The Agora series) and should be downloaded as follows:
Download the file, unzip it and place it into your main E-Sword folder (usually c:/program files/e-sword) Re-start E-Sword, then look in the reference section, accessed via the coloured three book symbol on the right of the toolbar. The Psalms will appear in the drop-down list.
