Nanotechnology is a hot topic in most science and technology libraries. The literature of nanotechnology is widely scattered across traditional disciplines. This paper provides an introduction for the non-expert to key terminology, reference works and indexes to the literature of nanotechnology.
The Oxford English Dictionary (OED) defines nanotechnology as "The branch of technology that deals with dimensions and tolerances of 1 to 100 nanometres, or, generally, with the manipulation of individual atoms and molecules." The field is older than one might think; the OED's first citation for the use of "nano-technology" is from a production engineering conference in 1974. The concept, if not the term itself, was described in a lecture by Richard Feynman to the American Physical Society in 1959, entitled "There's Plenty of Room at the Bottom." However, the field has really only taken off since the year 2000. Compendex shows only three records using the term in 1988, growing to 240 in 1995, 547 in 2000 and 8,493 in the peak year of 2006.
With that explosion of research interest has come a parallel explosion of "nano" terminology. Sometimes it seems as though every word in the scientific and engineering lexicons has had the prefix "nano" stuck onto it by a trendy researcher. Thus, we have nanotubes, nanomaterials, nanostructures, nanodevices, nanowires, nanoparticles, nanobiotechnology, and so on, all referring to artifacts on the 1-100 nanometer dimensions as in the OED definition. There is a temptation for a searcher using online catalogs, databases or full-text sources to try to do a comprehensive search using nano* as the search term. However, this is unwise -- the term "nanometer" (or "nanometre" in the UK) is a commonly-used unit of measure for wavelengths of light and may appear in articles having nothing to do with nanotechnology, even in a very broad sense. The searcher is far better off to identify the specific "nano" terms, which are applicable for the desired search.
Beyond the array of "nanothis" and "nanothat," there are some other key concepts in specific areas of nanotechnology that are worth knowing. For example, in nanoelectronics, the terms quantum dot and quantum wire are frequently encountered. These terms refer to structures of conductors or semiconductors whose dimensions are so small that quantum mechanical effects cause electrons to behave as if they were confined to a point or a line, respectively, with very different behaviors than in the exact same material in the bulk state. The term molecular electronic devices is also frequently used in nanoelectronics.
An older term for some types of nanoparticles, especially when referring to particles composed of single elements, is cluster. Atomic clusters frequently display properties significantly different from the same material in bulk, both in electronic properties and in chemical properties, such as catalysis of chemical reactions. A more recent term, frequently applied to arrays of atoms or molecules at less than the bulk crystalline level, is supramolecular. Supramolecular chemistry covers a wide range of materials, many of which have nanotechnological applications.
A very special type of nanoparticle is the fullerene. The name "buckminsterfullerene" was originally applied to a specific molecule containing 60 carbon atoms, whose three-dimensional molecular structure resembles a soccer ball, or one of Buckminster Fuller's geodesic domes in spherical form. The term has since been broadened to a whole class of compounds with similar structures, not necessarily spherical, not necessarily closed, and not necessarily composed of carbon. Related terms include fulleranes, fulleroids and metallofullerenes. Nanotubes, especially carbon nanotubes, are close chemical cousins of the fullerenes. Another important related term is endohedral. An endohedral complex has an atom or atoms or small molecule physically enclosed by the cage structure of a fullerene. These, too, may display unique electronic, chemical and catalytic properties.
Not only electrical engineering, but also mechanical engineering has been extended to the nanoscale. Here the preferred term is nanomachines, though nanobots is sometimes used for more speculative papers. Nanomachines are considered part of the broader field of microelectromechanical devices, frequently abbreviated as MEMS.
The OED definition above refers to the "manipulation of individual atoms or molecules." The principal methods for moving individual atoms and molecules grew out of techniques used to view structures on the nanoscale. These techniques include atomic force microscopy, scanning electron microscopy and transmission electron microscopy.
Nanostructures can also be created by designing subunits, which will arrange themselves in the proper pattern, pulled together by inter-molecular forces, like a jigsaw puzzle putting itself together in only one possible way. This concept is called self-assembly, and is inspired by the way biological molecules, such as proteins and nucleic acids, fold themselves and stack together to create units with the proper structural or reactive function. Indeed, some self-assembling systems make use, for example, of DNA units, to force the assembly of individual units into the proper three-dimensional structure.
As with many new fields that cross traditional disciplinary lines, nanotechnology does not fit neatly into any one Library of Congress classification number. Some of the key classifications for nanotechnology works include the following:

As for Library of Congress subject headings, relevant headings listed below are currently in use:
Reference works for nanoscience and nanotechnology have proliferated in the past few years. Here is a selection of notable titles:
Journals devoted to nanoscience and nanotechnology have been springing up like weeds in recent years. As of October 15, 2008, a search for titles containing nano* in Ulrich's Periodicals Directory yields 117 titles. Some of the more important titles and their publishers are listed below:
In addition many volumes of symposium proceedings from IEEE, SPIE and Materials Research Society (MRS) are devoted to nano topics and should be kept in mind.
