In Preface to The Excursion, when Wordsworth describes 107-line extract from unfinished first book of The Recluse as kind of of design and scope of whole Poem (x), he invokes a genre which would have been familiar to contemporary readers. M. H. Abrams, who builds his masterwork Natural Supernaturalism around this text, describes it as a poetic (73), an indispensable guide not only to Wordsworth's poetry but also to Romanticism itself, so clearly does it articulate deepest literary and philosophical concerns of movement (20). This claim rests on high argument and imagery of Prospectus, Wordsworth's announcement of his plan to surpass Milton's Paradise Lost by writing a visionary poem about the Mind of Man, / My haunt, and main region of my Song (96-8), and by reformulating ancient Biblical prophecy of a new heaven and a new earth as an apocalypse of imagination, simple produce of common day (113). Wordsworth's term Prospectus also links his manifesto with mundane realities of book trade. A prospectus in literal sense was a printed advertisement for a projected book, book series, periodical, or other publishing venture, circulated prior to publication (and sometimes prior to writing) in order to attract readers and obtain advance sales. Prospectuses were a marketing device that played a part in subscription publishing, a method of publication used for most periodicals in this period and for certain types of book, particularly expensive, specialised books and multivolume books or book series such as collected editions, encyclopaedias, and anthologies (Feather 14). Typically a prospectus would describe proposed work, explain reasons for publishing it, how it improved on competition, and what terms and conditions of sale were, including where order could be placed, how much it would cost, when book was expected to be published, and how it would be delivered to purchaser. If an order were placed, prospectus became in effect a contract of sale and might even be used as a receipt, with author's signature and name of subscriber. The prospectus could also contain specimen pages, a table of contents, endorsements (sometimes called sanctions), and illustrations, anything that might entice a prospective buyer or subscriber. Often prospectus would be printed on same paper and in same format as work itself, so that prospectus would provide a physical sample of book, not just an abstract description of it. This aspect of transaction was important: a material object as well as an intellectual product was being offered for sale, and book purchasers were attentive to formats, typefaces, paper quality, and other physical features, all of which would be specified on prospectus under Conditions of Sale. A prospectus could range from a single page to four, eight, twelve, or even more pages, but a typical length was four pages, and a typical format was octavo. Prospectuses were free-standing pamphlets, distinct from other forms of advertising such as newspaper advertisements, publishers' catalogues, and end-page advertisements, all of which were used in this period (Raven 283). Prospectuses would be sent to booksellers, librarians, and individuals, and distributed at public places such as coffee houses. Some publishers and booksellers had national networks of agents who toured country distributing catalogues and prospectuses. Often, though, authors themselves distributed prospectuses and received orders, and authors frequently wrote prospectuses, as authors still sometimes write their own jacket blurb. (Powers 135) And they were used on a wide scale: print run of a prospectus might be many times that of work itself. The intended publisher of Coleridge's journal The Friend (which eventually acquired around 650 subscribers) advised that 10,000 copies of prospectus be circulated in advance, with another 2000 per month for each new issue (I. …
