Abandoned mine records
Where the workings are, and the office that holds the mine maps.
From the old mine records
The mine records hold 9 mine sites inside the county: 4 past producers, now closed, 1 prospect or occurrence that was never worked, 1 site producing when the record was made, 3 processing plants, which are not workings; the old survey maps add 53 holes drawn inside the county, 0 of them shafts or tunnels. The minerals the records name are construction sand and gravel; Wollastonite.
A point in either file is a location, not a property line: the sheet shows the opening on the surface, not the rooms under it. The record that shows what runs under a parcel is the mine map. The OSMRE National Mine Map Repository holds scanned underground mine maps and answers requests for a named mine or an area. New York has no coal AML program; the DEC database covers permitted mines, not historic underground workings.
Rows taken off the old survey maps open the USGS record of what sits at that spot, because no single feature on those maps has a page of its own. Rows from the mine records open their own USGS page.
New York abandoned mine maps ranks every county and town in the state by the workings recorded inside it, names the office that holds the mine maps, and says what to do if the ground moves.
Disclaimer: The mine information here is for general information only. Old mine records can be incomplete, outdated or wrong, and finding nothing here does not mean there is nothing there. Check with the mine map office named here before you rely on it, and have a qualified engineer look at any ground you are worried about. PublicRecordCenter.com assumes no responsibility or liability for any errors, omissions, or consequences arising from the use of this information.
Know before you ask
Each figure below was read on the official source linked beside it, October to November 2026. A fee or rule the source does not state is left out rather than guessed, and offices can change their schedules, so confirm on the source before you pay or travel.
The County Clerk's deed-copy instructions use the section, block and lot to locate the instrument. A certified deed copy costs $10 including the listed $5 search charge. The office distinguishes document retrieval from recording a new transfer; do not apply a deed-copy amount to mortgage recording or transfer taxes.
The Clerk's vital-record guidance directs birth and death requests to the municipality where the event occurred and marriage requests to the office that issued the license. The county's historical marriage collection covers 1907 through April 29, 1935. Authentication of a municipal signature is a different service from issuing the underlying certificate.
The Clerk divorce request form requires the specified party or attorney eligibility and a notarized mailed application. Certified copying costs $1.25 per page, with a $5 minimum and $40 maximum; include the required cover page. A missing index number adds the listed $5 search charge. Its stated processing window of up to 4 weeks concerns this court-copy service, not local birth certificates.
The Nassau court directory places Family and Matrimonial Center operations at 101 County Seat Drive following the June 2, 2025 move. An old Westbury Family Court address should not direct a new visit. Check the assigned division and floor when the case concerns family or matrimonial proceedings.
The District Court listing gives a $15,000 civil limit and a separate $5,000 small-claims limit. These are jurisdiction descriptions, not fees. Its case-type instructions identify the departments handling civil and other District Court matters.
The Assessment Department publishes its office on the fourth floor of 240 Old Country Road. The Board of Elections is on the fifth floor of the same building; record types still require separate requests. The Sheriff's Correctional Center is in East Meadow, not in that county-office building.
For ordinary administrative records, follow New York FOIL and the responsible agency's submission route. A court-copy application and a restricted certificate request use their own eligibility rules. The New York guide lists state services for requests beyond the county.

Labor Department file
The U.S. Department of Labor's Wage and Hour Division closed 2,578 investigations in Nassau County since fiscal 2005 and recorded $60,531,417 in back wages agreed for 33,757 workers.

The 25 employers with the most back wages agreed, of 2,130 on the Nassau County record; 969 employers have a page of their own and open from the table, the rest show their whole record here. The 2,105 more with smaller records are on the New York wage theft records page, whose search answers for every employer in the state.
Straight answers
Open only the answer you need.
Booking photos are kept by the agency that made the arrest, such as the Nassau County Sheriff or a city police department in Nassau County. Ask that agency for its record. Under New York Public Officers Law 89(2)(b)(viii), releasing law enforcement arrest or booking photographs is an unwarranted invasion of personal privacy unless public release will serve a specific law enforcement purpose and no state or federal law bars it.

The deed-copy instructions call for the section, block and lot. A certified deed copy costs $10 including its listed $5 search charge; new recording fees are a different product.
The Clerk vital-record guidance sends those requests to the municipality where the event occurred. A county authentication of a signature does not replace the certificate itself.
The record-custodian instructions direct the request to the office that issued the license. The county also identifies its separate historical marriage holdings for 1907 through April 29, 1935.
The request form asks for it and lists an additional $5 search charge if it is absent. The form also specifies eligibility, notarization and copy charges.
The court directory identifies 101 County Seat Drive, Mineola, for the move effective June 2, 2025. Confirm the court division and floor before a visit.
The current court listing states $15,000 for civil matters and a separate $5,000 small-claims limit. Use the appropriate court and case category.
No. The Assessment Department occupies the fourth floor at 240 Old Country Road. The Board of Elections has its own office and record responsibilities.
The Correctional Center publishes visiting sessions for its East Meadow facility. Those hours should not be reused as a general public-records counter schedule.
