INSTRUCTIONS: How to filter biblio entries by URL

http://ismaili.net/heritage/doc/type/101 ...will show only book chapters http://ismaili.net/heritage/doc/place_published/Toronto ...will show items published in Toronto basically, you just construct the url with field/value pairs, where the field name is the name in the biblio table with the "biblio_" part omitted. From the two examples above, there is a field in the biblio talbe called biblio_type which holds integer values representing the publication type, and there is a field called biblio_place_published which holds a string representing the place published. You can combine them like this... http://ismaili.net/heritage/doc/type/101/place_published/Toronto to show only the book chapters published in Toronto. The available db fields are as follows... `biblio_type` int(11) NOT NULL default '0', `biblio_number` varchar(10) default NULL, `biblio_section` varchar(10) default NULL, `biblio_other_number` varchar(24) default NULL, `biblio_secondary_title` varchar(255) default NULL, `biblio_tertiary_title` varchar(255) default NULL, `biblio_short_title` varchar(255) default NULL, `biblio_alternate_title` varchar(255) default NULL, `biblio_translated_title` varchar(255) default NULL, `biblio_authors` varchar(255) default NULL, `biblio_secondary_authors` varchar(255) default NULL, `biblio_tertiary_authors` varchar(255) default NULL, `biblio_corp_author` varchar(255) default NULL, `biblio_other_author_affiliations` varchar(255) default NULL, `biblio_edition` varchar(255) default NULL, `biblio_publisher` varchar(255) default NULL, `biblio_original_publication` varchar(255) default NULL, `biblio_reprint_edition` varchar(255) default NULL, `biblio_place_published` varchar(255) default NULL, `biblio_year` int(11) NOT NULL default '9999', `biblio_volume` varchar(10) default NULL, `biblio_number_of_volumes` varchar(10) default NULL, `biblio_pages` varchar(128) default NULL, `biblio_date` varchar(16) default NULL, `biblio_isbn` varchar(24) default NULL, `biblio_issn` varchar(24) default NULL, `biblio_lang` varchar(24) default 'eng', `biblio_abst_e` text, `biblio_abst_f` text, `biblio_full_text` tinyint(4) default '0', `biblio_keywords` varchar(255) default NULL, `biblio_url` varchar(255) default NULL, `biblio_doi` varchar(100) default NULL, `biblio_issue` varchar(10) default NULL, `biblio_type_of_work` varchar(255) default NULL, `biblio_accession_number` varchar(24) default NULL, `biblio_call_number` varchar(24) default NULL, `biblio_notes` text, `biblio_coins` text, `biblio_research_notes` text, `biblio_custom1` text, `biblio_custom2` text, `biblio_custom3` text, `biblio_custom4` text, `biblio_custom5` text, `biblio_custom6` text, `biblio_custom7` text, `biblio_auth_address` text, `biblio_remote_db_name` varchar(255) default NULL, `biblio_remote_db_provider` varchar(255) default NULL, `biblio_citekey` varchar(16) default NULL, `biblio_label` varchar(255) default NULL, `biblio_access_date` varchar(255) default NULL,
