The city register of the city of New York and the various county clerks shall procure, at the expense of the city or county, a file to be styled and labeled "Federal lien notices", and an index book or card index system or computerized index system to be styled and labeled "Federal lien index." When a notice of any such federal lien is presented to any such officer for filing, he shall endorse thereon his serial number and the date, hour and minute of its receipt, file it in numerical order and shall enter it alphabetically in the federal lien index. The entry shall show the name and residence of the taxpayer named in the notice, the aforesaid endorsed serial number, the date of filing and the total amount of the lien, including interest and penalty.

The entry shall show the name and residence of the taxpayer named in the notice, the serial number, if any, of the original recording officer, the date of original filing, and the total amount of tax, interest and penalty shown on such notice.

4. On or before November first, nineteen hundred eighty-seven, the secretary of state shall cause a search to be made of the records of the clerk of each United States district court within the state for notices of federal liens filed therein from January first, nineteen hundred seventy-four until the effective date of this subdivision. On or before December first, nineteen hundred eighty-seven, the secretary of state shall file in his office such information as is required pursuant to paragraph (a) of subdivision two of section two hundred forty of this article and shall forward to each county clerk the notices of federal liens affecting real property situated within each such county or affecting a lienee who is a resident of each such county or if there are none, a certificate so stating, which information shall be filed by the county clerk on or before January first, nineteen hundred eighty-eight. Each county clerk shall maintain such documents in a file styled and labeled "Federal lien notices filed with the clerk of the United States district court for this county subsequent to January 1, 1974." Each such clerk shall also receive and maintain in such file any certificates and notices which affect such documents and which may be filed pursuant to section two hundred forty of this article at any time in the future. Each such county clerk shall procure at the expense of the county an index book or card index system to be styled and labeled "Federal lien index of liens filed with the clerk of the United States district court for this county subsequent to January 1, 1974" and shall enter therein a record of each such notice of lien or certificate and any notices or certificates received thereafter affecting such documents. The entry shall show the name and residence of the lienee named in the notice, the serial number, if any, of the original recording officer, the date of original filing, and the total amount of lien, including interest and penalty shown on such notice. Whenever the federal lien index prescribed by this subdivision shall be recopied or reindexed, the entries therein shall show the information required by this subdivision. Notwithstanding any contrary provision of this subdivision any county clerk's office having the capability of incorporating such documents into existing federal lien records may make such incorporation rather than creating and maintaining the separate files required by this subdivision.
